Ta'ult whom it may concern: Be' it known that I, ADELMER M. Bares, "a citizen of the United States, residin at Chicago; in the county of Cook and tate of lllinois have invented a certainnew an useful Improvement in Bag-Tying Ma- .chines, of which the following is a specifibation. I

My'invention relates to improvements in,

Y B is a hub rotatably mounted on theshaft A. It is provided with a pulley B- adapted to be driven by a belt B. hy any suitable here shown. The collar B en-"G gages one end of the hub and limits its movement with respect to the shaft in a'leithand direction. B is a clutch ring inte ral with the hub B. Thehub. B is prism] to clutch disk B partially withinthe clutch" ring B. The clutch, lever 'B isrotatahl'y mounted in a groove B in the hub B and extends outwardly within' a slot B inthe shown in Fig. 11, so that the clutchshoulder B tends normally to engage the inner periphery of the clutch ring 13* and asthe clutch ring is driven in the direction oftlie arrow, tends to clamp the rin and disk8 together to drive the disk and s aft in response to the rotation of the ring. 13 is a stop on the base A, projecting upwardly and adapted when the parts are .in position shown m Fig. 1, to project into the path "of the do 13".

pin D rojecting rearwardly toward the clutch. otatably mounted on this pin is a hub D havin a star wheel D thereon. pin D in the ace of the clutch disk B pro Jects into the path of the star wheel and is adapted to engage and intermittently rotate that wheel. D is a cam on the hub D. D is a cam roller carried by a bell crank. Lever D is held yieldingly inengagement with the cam at all times by a spring D which tends to rotate the lever about its pivot position on the rod D, and to draw the stop or trigger end D of the lever, against-the surface of the hub C.

It'will be evident that, while I have shown in'ln'y drawings an operative device, still many changes might be made in size, shape and arrangement of parts without departing materially from the spirit of my invention. I wish therefore, that my drawings be regarded as in a sense diagrammatic.

The use and operation of my invention are as follows The operator with the parts in the position shown in Fig. 1, inserts the open end of a bag into the space between the spring fingers, drops the. tie in position at the ends of the fingers and then withdraws the bag against the tie puckering the bag and forcing it into the U-shaped loop thus He continues to pull on this loop and draws the parts into the position shownin Fig. 2, thus disengaging the dog on the clutch lever from the stop. The

' lever-out of'engagement with the stop on quarter of a revolution spring rocks the clutch lever into the driving position, and the shaft driven by the belt rotates, twisting the spring forks and winding or twisting the tie up on the neck of the bag.

I will now refer to the mechanism illus trated inFigs. 3 to 1.0 which has as its object to stop the rotation when the necessary numberof twists-has been made. Preferably three complete turns are enough for the tie. Figs. 3 and 4 show the parts in the position shown in Fig. 1. "As' soon as the operator starts the machine, the rotation of the clutch pin carries the parts into the position shown in Fig. 5. This rotates the cam through one and pulls the stop the floating'sleeve. The driving tooth on the clutch hub passes on into the position shown inFi 6. Thus at the end of the first quarter revo ution the parts are disengaged "as/shown. The next fall revolution from the position shown in Figs. 5 and 6 to the position shown in Figs. 7 and 8- brings the driving. tooth around against the tooth on the floating sleeve. It carries them both around a short distanee into the position shown in Fig. '8. The next full revolution brings the parts into the position shown in gs. 9 and 10.. The cam having now made one half revolution, thestop lever again is -clutch interposed between the shaft permitted to be forced by the spring into enga ement with the sleeve.

ith the parts in the position shown in Figs. 9 and 10, the stop lever resting against the floating sleeve in the path of the stop on the sleeve, the parts rotate into the position shown in Figs. 3 and 4. The stop-on the" sleeve engages the top of the stop lever. The sleeve can no longer rotate. The clutch continues to rotate and the driving tooth slides down the cam or inclined surface of theslcevc tooth and the parts are thrust into the position shown in Fig. 1. This brings the dog onthe clutch lever into engagement with the stop on the base and causes the clutch to trip. Rotation then stops with the parts shown. in the position of Fig. 1 ready for the next operation.

I claim:

The combination with a shaft and a pulley rotatably mounted thereon, of a clutch interposed between the shaft and pulley, the shaft being slidably mounted, a control lever projecting from the clutch, a stop in the path of the lever, means responsive to the will of the operator for movin the shaft to bring the stop out of line with the lever, and automatic means for moving the lever back into line. with the stop.
